in place ofL
. There's no functional difference. lpe:CD<L.>
means camera with diffuse scattering event for light scattering type.lpe:CO
means camera with emissive objection (since emissive does not need any light, there is noL
).- Using
.
in in place of[DS]
is shorthand, if you are using a User Lobe, you must specifyU
and cannot use the.
shorthand lpe:CS*D*[LO]
means all light paths minus caustic light paths. While caustic paths (defined here as diffuse followed by specular) may contribtue significantly to the final image, they are a common source of fireflies and flickering.- Similarly,
lpe:CD+[LO]
means all diffuse light paths minus caustics andlpe:CS+D*[LO]
means all specular light paths minus caustics.
